Initial Boot Process

Note
All new line cards are designated as administratively down by default. Port Status LEDs are off until you
configure the interfaces and use the no shutdown command.
During a typical line card boot process, the following events occur:
1. The line card receives power and begins executing initialization software.
2. The line card performs internal checks, and prepares to accept the Cisco IOS XR software from the RSP.
3. The RSP loads the line card with its Cisco IOS XR software.
To verify that the line card is working properly:
1. Check that the Card Status LED is on (green) to verify that the card is operating normally.
2. Check that the Port Status LED for the port of interest is on (green or blinking) to verify that the port is
active. If the Port Status LED is not on, verify that the associated interface is not shut down.
3. If one of the conditions above is not met, see
any possible problems.
